An interesting combination of speed, dexterity and bluff. For each match there will be  a provocateur that, putting a numbered card in the arena,  will challenge the other players.  The other players throw a numbered card into the arena, too; the card to be valid, must be of a different value and must land covering the opener neatly. Once the participants of the duel are decided,  the two players must choose if making war or  peace. They have a duelling block, showing peace or war., that will be reveald at the same time. Peace-peace means the players swap the cards in the arena. War-peace means war takes all the cards but loses 1 of 10 lives. War-war means no-one gains cards and both lose a life.
